best nitro tuning vid ever

This. THIS is the video. Nothing left to change. No “close enough” solid, methodical and a step by step proceed. Giving all the “why’s” bang on video, man. Thank you. We have the same brain. Yours just has this info that mine didn’t. Very understandable.
Thank you thank you thank you. I have been in this hobby for 11 years and wasn’t able to get a race tune on a vehicle until seeing this video. Thank you for your work
From far the best video ever on how to tune a RC nitro engine, just brilliant !
Touche, I couldn't have explained engine tuning any more thoroughly. I had a big bag of popcorn 🍿 during this. 2 👍👍 up. You have a bright future in RC youtube ahead of you🏎💨💯💪💪👊👊👍👍
Thanks for taking the time to share the knowledge. Nitro rc cars are almost rare in 2023. I walk into local hobby shops with my vintage traxxas or even my ofna racing buggy and they look at me like Im crazy. They dont even have any nitro for sale. They try to push electric on me. They have little to NO knowledge of nitro. Wont even look up parts for me half the time. Whats funny is as soon as I fire one up. Everyone in the store comes running. They always want to see them run. Was tuning my traxxas earlier this week I had an entire construction crew of guys hooting and hollering. I let them drive it around a bit and they looked like kids at xmas.
After running these things for 12 years, I think you just shown me the easiest way to tune that I had never heard of. Its so logically sound that I'm going to try it out right after this.

It's been two years so I figured I would check in. I did follow through and I can say without a doubt that this video definitely improved my performance at the track. I rarely, if ever, flame out in a race and the car just works. The brakes are never trying to overstep the engine or vice versa. The engine always reliably comes back to idle and the brakes don't stall it. Thank you for this video!!

@@wolf16731Awesome. Thanks so much for coming back for an update! 👍
Possibly the best tutorial video ever in tuning a motor. That double idle as haunted me for years, looking forward to trying your method out. I wanted to take a minute and say "thanks" and well done on the vids. The editing and the funny moments make for an enjoyable experience and learn something along the way. Great work! Subscribed too.
By far the most comprehensive video on nitro engine tuning I’ve ever seen. This video is going to help so many people learn how to properly tune their nitro engine. Great work 👍
You delivered as expected! This video blows all other tuning videos away. I love how start with the theory (very good visuals of the engine and carb btw) and then move on the practically side of tuning. This is a must see for everyone who is still struggling with tuning. Also the production of the video is very good. 10/10! I’m looking forward to the next one.
Absolutely GENIUS! I not only watched every single portion of these videos broken down, i just watched this entire video fully! So awesome and i can't wait to get my Truggy fired up & Tune my Team Orion engine tuned
Havent Had Time to watch the Full length yet, but what I can say this is the benchmark tuning Video and will help a lot of people. Proud to be a patreon of your Project since a Long Time. Great job JQ! I have heard so much scrap at the tracks about tuning and some pros who never told there methodic or told wrong infos to the people. This video brings Light in the mystery of engine tuning.
A rather long video, but extremely helpful. A lot of other videos I've seen on the topic seem to "gloss over" the specifics. Being able to see the change in comparison to good/lean/rich is super helpful. I've not purchased a nitro before, but this certainly is helping me get the confidence I need to make the leap into nitro. Can't thank you enough!
First class. I learned so much from this. I love the logical, progressive way it is presented. Can’t wait to apply these concepts to my tune! Greets from 🇦🇺 😎
best nitro tuning video ive ever seen!! thanks for this really. and this is coming from a guy who ONLY has nitros over 25 of them and this was a great help.
Thank you so much for putting the time and effort into this video. I got my first nitro 14 years ago as a kid, didn't really understand it. Ran it into several car tires and destroyed it. During the pandemic, I found it in my parents basement when I was visiting and decided to rebuild it. I am having to learn everything and this video is finally helping me understand tuning like never before. This is my second time watching this currently, so thanks mate!
Absolutely awesome explanation! Really takes the guesswork out of tuning. Makes me wanna go burn some nitro and wake the neighbors :) Keep up the great work, looking forward to more.
Thank you JQ, When I got Into this hobby 12 years ago I went with electric buggy’s because when I would go to the tracks, nitro vehicles were always having trouble starting, running and finishing. After a couple hours and 4-5 battery packs later when I’m leaving, I’d see the nitro guys still trying to tune and run their vehicles...SMH. Your detailed explanation is something I get and understand, I now have a better understanding and will look at trying out a nitro buggy... again Thank you!!
This video was actually really helpful, and I like how he broke it down in many different ways and examples. The open carberator example put things into a better perspective. Thanks for making the video
I'm so happy I discovered your channel and watched this video in it's entirety! I just got an old Revo with an OS18TM and it hadn't ran in almost 10 years, and I had no clue what I was doing trying to tune it. Thank you bro! Liked, subscribed, and shared!
Thank you JQ for putting together a very professional video together with some laughter in it. Normally the videos I have seen on how to tune a motor you can’t hear 👂 the person. Every detail you explained really help me understand in detail how the motor works. What I need to listen to and what the motor is doing. A+. Keep the videos coming. For 5000 subscribers put out a JQ black ED kit

For someone who has struggled a lot with the tuning, this video is the light. Thanks man. There's no other video like that in the planet. For sure..You did the difference. Thanks..
This was the most informative video on tuning I've seen.....along with the inner workings of the carb which helped understand the tuning tremendously. Thanks so much JQ!
This is by far the most detailed explanation on how to tune an engine. There is a lot here but my biggest takeaway was the idle gap and how to set it. Keep the content coming please!

Awesome video! Got into the hobby 25 yrs ago at the age of 8. So much trial and error with tuning. This is perfect for anyone entering the hobby.
This is pure gold! Coming from the grounds up to the top, brick by brick. This is THE BEST carb tuning guide ever! Congrats, mate! And thank you...
Bro this is one of the best rc vids I've seen. More please 💯
Top top top!!! I love the format, fun and really technical... Good job JQ
Hat off to you sir. You do know what you doing. I messed with carb for 1 hr based on your recommendations, and tuned it so well, i never seen this tmaxx run this good. 👍
This is DAMN good advanced Nitro tuning advice. 👌 It took me years of playing with Nitro R/C engines to learn how to tune like this. This video will save you all those years of learning, and pack it all into an hours worth of your time. WELL worth the watch if you want to learn to tune like a pro... Cheers for the time you invested into this excellent video! 👊 🍻
This is the definitive guide to tuning nitro engines. I can't believe I've been looking at this for free... Thanks for all the effort you've put on making it, you did a great job.

Now you have a reason to start again
I think this video saved me from a more than a few screw ups over my first full nitro season, thanks!
Your explainations are so clear that it actually makes me want to try nitro again, 20 years later. I really appreciate the jokes and the light tone but also the fact that when you are explaining a technical and somewhat difficult aspect, you stop with the banter. Some vids on YT are just annoying with too much editing and meme references. Please keep on making these vids!
For measuring the idle gap: The shank end (the part that goes in the drill chuck) of a precision drill bit or what are called 'pin gauges' would be an easier tool to use. They are round and fit in that space more easily. The pin gauges would most likely be more expensive, and are precision measuring tools machinists use for gauging similar situations. The precision drill bits come in small sets and cane be found at many places dealing with hobbies and crafts. Just measure the shank end of the bit with you calipers ( most of the time the shank is slightly smaller than the labeled drill bit size )

I'm so new to nitro, and I bought an OS 11k R for my revo 3.3 and you are saving me. This is great stuff
This has to be the most in-depth RC engine tuning and tutorial on KZread. I don’t care what they say about you..Your alright in my book JQ.
This was the best tuning guide I’ve ever seen, you really now your sh*t 😄👍🏻 Greetings from 🇸🇪👊🏻
I can understand this. Very clear and precise, thank you. This is an awesome channel, I like you mix some laughs in there too. 🤣
I have to say it again because I’ve watched this video maybe 4 times now, great job. This has helped me tune a brand new engine after a break in, it is my very first nitro car. Excellent information.
Great video, I now i have the confidence to tune my own engine. I was so tired of asking guys at the track and hoping it was done right.
Great video keep them coming how bout gearing, clutchng,

I've been casually searching 'how to tune nitro engines' information for over 20 years.. hoping to find a couple of missing insights needed to up my tunes beyond the basics... I Finally found it! Brilliant, Thanks.
Best nitro tuning video out there, answered all issues you could have tuning a nitro engine.
One of the best guide ever. Finally i understand de sound of my gtx18 engine. Today fine tuned my kyosho dst rc car. Thx!
That's great amount of precious knowledge. Thank you thank you. I've just bought my first nitro rc and waiting for package. After tunning it will go at least 200 stechokilometers/h!
This is one of the best RC videos on KZread, period. Thanks, JQ. Amazing video, I learned a lot.
I love this video im only on my first season with nitro , anybody that has shown me anything about tuning they just say this is how you do it and dont explain it at all
Thanks for the video JQ. As a average joe racer i found your video extremely helpful. . I’ve never seen or heard of any video that explains everything and goes into such detail about tuning a nitro engine. It’s very very easy to understand. I can’t wait for more of your videos to come out.. Thank you

Been tuning for over 20 years, This video explains it perfect
Thank you so much. Just got a 1/16 blur and I did the break in thanks to u, I made a mistake and messed up my carb settings and was able to get it back and running thanks to you. I greatly appreciate!!!
Great breakdown on every part of the process. Showing the problem, explaining why it's doing what it's doing and how to correct it. Perfect, it makes it easier to diagnose the majority of issues with nitro. Thank you.
Honestly I didn't think I would learn much from this but the way he broke every little step down honestly surprised me. Definitely DEFINITELY worth a watch. I was having all kinds of issues trying to tune my nitro engine but now I know for sure I can start from scratch and get it right. Thank you for all the information and keep up the good work!👌🤘
As a complete noob in nitro racing this is a god send. Thank you very much! The split open carb answers so many questions i had. The way you add all this extra contextual information about the why is very enlightening. I'm certain this video helps out the RC nitro hobby a lot. Again thanks! I will be buying your book. Suggestion for a new video: How do different pipes effect the performance of an engine.
I just wanted to say I’ve followed this video closely and it truly works. No two stage idle the engine has never run better. Thank you so much.
Thank you so much for this video! Re tuned my engine with your procedure and worked great! Power was unleashed!
Thanks JQ, awesome video. I am electric guy, but I like nitro engines and this is very informative and clear. Super job with tuning. I like the way you comment videos and not talking over running engine. 🏆🥇🤩
This is the best video I have ever watched regarding tuning..thanks for taking the time to do this! Looking forward to more vids 😀
Excellent video, been in the hobby for 30 years, great advice to pass on to and show my girls who have just started in the world of rc, thank you
Wow!!! Very impressive explanation and carb cutting and painting! I will direct customers to this video and channel no question. At the track I sometimes use my 0.5 allen driver to adjust slide in carb in a pinch.1 hr ccw or cw to adjust idle gap. Feelers are the best tool for sure!!! Well done sir well done!
Superb video. Just wish I had seen this before messing around and changing all settings on my carb meaning it won't run! Will use the knowledge now to get it running so thank you. Brilliantly edited too!
I remember some years back when you were working on your prototype car. I was thinking about getting into 1/8th nitro. I have always been an AE guy, but I wanted the JQ car because it was new. Very cool to see that you have gone this far, Good Luck! I only watched 5 min of the video, for others reading, but there is a pro secret at 4 min 45 seconds.
Great video and thank you for the work and time you put in it! So far I have been satisfied with the set-up and performance of my engines. But now I know how to detect small inaccuracies and how to fix them! That helps a lot!
Fantastic video. I wish ppl who think they are good tuners would watch this because JQ nailed it with the 2 stage Idles are not ideal and you want to achieve a single stage idle at all times. I love how he goes into great detail of tuning a Nitro Engine. 100% Dead On Balls Accurate. Thank you JQ for a fantastic video.
Dude, the sounds and stuff helped so much. I've always ran a rich LSN and lean HSN, the high idle after widr open throttle I always thought meant LSN was lean..... Thank you so much brother
Extremely helpful. I will be running nitro next season and look forward to applying the info given in this video.
This will be helpful when I get to race a Nitro for my first time next weekend... less than 10 days to get up to speed and make this 2wd gas truck go BRAAAAAP!!! Thanks again for your content.
Even though so many people talk crap about you, I got to say you are the best. Amazing tutorial!
Excellent video the best I’ve ever seen by far finally someone teaching you how to get rid of a Two step idol after watching this I feel like I will have my nitro is running like they should so yes you can call it a secret because I think it’s gonna work for me now
TON OF of great information here! I'm just getting into the hobby and picked up an older Tamiya Mad Spirit w/ an FS12-f engine. This thing is giving me the run around trying to tune it and get it running properly. My biggest issue is how little info is out there on this engine. At least I understand it better and can approach tuning more informed thanks to your video
After watching this video.. it really help me years of engine tuning problem.. with this video, now i really understand what are all the function of each needle. Also helps me what are the steps in tuning the correct way of my nitro engine. A big t.q bro...
Oh wow! Im at work now, but really looking forward to watching this video! Thanks for posting!
Thanks I've really searched trying to tune my engine so I know your video will get mine running after a year of trying to get it right. I got three and 2 years two has set video reminded me setting in college you explained so well. I wish I could ask a question.
JQ, this is probably the best video anyone has ever made regarding how to properly tune an engine. I started racing 8th scale nitro buggy when I was 17. I am now 30. Only after watching this, do I fully understand how to properly tune a nitro engine. The explanations and analogies you provided helped everything make sense. For me, there was always something slightly off about the tune on my engines when I raced, and I would just accept getting an engine in the ballpark. I wish this video would have been made 13 years ago :) Subscribed!

Followed and paused as i pulled mine apart and rebuilt. Apart from the fine or heat applied lol. Brilliant thanks heaps.
Neat how every screw on that carb has an o ring on it. I've got a 20 year old Ofna with a Force 3.5 and its carb has a high speed needle and mixture control valve but no low speed needle. It's been a lot of fun to work on and learn tuning on. Thanks for the great video.
That's by far the most helpfull video to tune a nitro engine the right way. Thank you so much 🙏🏻
Absolutely fantastic and comprehensive guide. I finally managed to tune my Thunder Tiger EB4 s2.
Awesome video JQ, very well and eloquently explained. Learned a few things even though I've been racing nitro for a while.
This is some of the best content I have ever come across. This video is gold. Thank you,
All I can say is wow! Thank you for sharing this, hands down the most informative tuning video ever.
You are the best!!! Run electric here. But, I want to get into nitro and, I feel comfortable now with your help. BIG THNX!!! SUBCRIBED!
This is absolutely the best nitro tuning video I have ever seen, thank you very much
Thank you for sharing your information on the carb really helped me understand why I couldn’t set my carb now I can Thanks again great video
believe me, I am playing with nitro RCs for more than a decade and now I know what is going on inside the engine amazing knowledgable video
Without doubt the best video on tuning my nitro car that I have seen. Great find. Well done!!
I was about to give up with nitro, because I just could never get a reliable tune, or sometimes couldn't even start my engine. I watched every video I could find, and tried to find articles that explain what the needles actually do, but nothing I found properly explained what's physically happening inside the engine. Very frustrating! I'm so excited about having an actual handle on what's going on now. Thank you so much for making this! 🤘
I’m just getting in to nitro rc cars so I found this more than extremely helpful because much like my big cars I want it to run perfect every time
Excellent video!! cut section of the carb was a great idea, helps visualize really well 👍🏻 I dont think anyone can go wrong with tuning after watching this video!!
Like many have mentioned, this is the best Carb (or is it carburateur) tuning video out there. Well done!
This video was the best got my car going flawlessly in 5 mins after watching this video thank you so much
I always watch the video when I jump back into nitro rcs. Im one of those guys who doesn't have a dedicated hobby I'm all over the place lol This detailed video is so helpful I just jump to the parts I need to review.
Thank you so much for the time and hard work this video obviously took to create, it is a fantastic educational video. Already understanding many nitro fundamentals I have never heard anybody explain the two stage idle and never understood it, but kinda just accepted it. I can't wait to attempt to tune it out of my engines.
I have never seen such a great breakdown of tuning. Great, this has really helped me. Thank you.
I learned so much from this video, Thank You for putting this together. I had a hard time tuning my Nitro Buggy because I was new and there are no tracks near me to get any information so everything I could find was on KZread. No other video explained why my idle was reving high but would drop after a couple of seconds or a blip of the throttle. Now I know it was the HSN was to lean, I richenend it a little, and got the LSN straightened out, now it idles propely.
Hey JQ, my 3rd time viewing this video as I have moved on to much better engines and different needs from them. I took many notes this time! So when I am outside and it does this or that, I can refer to the tuning manual which you’ve provided and hopefully get it right far quicker! Thanks again, and for the record, I’m American and hate that we don’t use the metric system!!! Have a good one, I’ll be referring anyone I know to this video! 👍
